Layer-Hybridized Wigner Crystals in MoSe2/WS2 Moiré Superlattice
Tianyi Ouyang, Yuze Meng, Li Yan +11
Transition metal dichalcogenide moiré heterobilayers with type-II band alignment provide a versatile platform for layer-polarized generalized Wigner crystals, in which strong Coul…
Superconducting cavity probes sliding ferroelectricity in small-angle twisted WSe
Krishnendu Maji, Supriya Mandal, Sriram H. +8
Ferroelectricity is a property of materials that exhibit spontaneous charge polarization. Ferroelectricity in 2D materials is interesting because of their applications in memory de…
Layer-parity-defined surface polarization in NbCl for excitonic modulation at van der Waals interfaces
Xinyue Huang, Hansheng Xu, Yuchen Gao +10
The intrinsic symmetry breaking in the breathing kagome lattice of layered NbCl provides a unique mechanism for realizing electrically polar surfaces. In each monolayer, th…
Ferroelectric-tunable quantum nonlinearity of chiral Bloch electrons in a moiré system
Zitian Pan, Jundong Zhu, Yu Hong +7
Sliding ferroelectricity in van der Waals materials shows great potential for designing robust memory devices. However, its thermodynamic behaviors and the coupling with certain qu…
Ferroelectric hysteresis in singly aligned graphene-hBN moiré superlattices
Bao Q. Tu, Tanweer Ahmed, Garen Avedissian +7
Ferroelectric materials have the unique ability to maintain an electric polarization which can be reversed under an external applied electric field. This property makes them valuab…
Multiple Superconducting Phases in Rhombohedral Heptalayer Graphene
Chuanqi Zheng, Chushan Li, Chenyu Zhang +14
Crystalline rhombohedral multilayer graphene (RMG) has emerged as an ideal platform for studying unconventional superconductivity. Here, we report the observation of superconductiv…
